Produce superior jack by accumulated individual know-how and technology |
 |
 |
We have given consideration to easy selection of our products, and then we changed the former jack type number into capacity indicate number. | |
|
Capacities are developed more than 25% (maximum 67 %) as compared with the previous machines. | ||
|
We introduced our industrial patented screw stopper key system which is optional specification of ball screw type. | ||
|
We make compressive load and tension load equally capable for products with its nominal capacity from 2kN to 2000kN. | ||
|
Measurements of screw shaft end design are unified and standardized. |
